Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors w ....Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors will be used to devise a simple portable colorimetric test that can be performed in the vineyard or the winery. The ability to rapidly determine the level of grape contamination with phenolic glucosides would give Australian wine growers and wine makers a powerful tool to mitigate the effects of bushfires.Read moreRead less

Summary
Development of electrochemically activated sorbents for PFAS defluorination. This project aims to develop a new treatment technology to completely defluorinate per- and poly-fluroalkyl substances (PFAS) and to treat significant water quantities. The majority of existing water treatment technologies are unable to remove PFAS to the desired extent, are prohibitively expensive or are only useful for a very limited lifespan. This project is expected to develop a new treatment technology with the abi ....Development of electrochemically activated sorbents for PFAS defluorination. This project aims to develop a new treatment technology to completely defluorinate per- and poly-fluroalkyl substances (PFAS) and to treat significant water quantities. The majority of existing water treatment technologies are unable to remove PFAS to the desired extent, are prohibitively expensive or are only useful for a very limited lifespan. This project is expected to develop a new treatment technology with the ability to completely defluorinate PFAS, treat significant water quantities and help address many of the pressing concerns facing water treatment operators. This technology is also scalable, and can potentially be used to treat significant quantities of contaminated water.Read moreRead less
Gut Absorption of Constrained Peptides for Local and Systemic Targeting. Aims: This project aims to investigate how peptides are absorbed across the intestinal wall and distributed to organs and fluids in a rodent model by combining bio-analysis and pharmacokinetics with high-resolution microscopy and imaging.

Thioamide ligations: new technologies for peptide and protein synthesis. This project aims to develop novel amide-bond forming reactions for the chemical synthesis of peptides and proteins. New peptide ligation strategies, including an asparagine-based ligation and a residue-independent ligation will be developed that exploit the recent discovery of silver-promoted coupling reactions of thioamides. A novel late-stage, chemo-selective assembly of N-glycosylated asparagine residues in peptides and ....Thioamide ligations: new technologies for peptide and protein synthesis. This project aims to develop novel amide-bond forming reactions for the chemical synthesis of peptides and proteins. New peptide ligation strategies, including an asparagine-based ligation and a residue-independent ligation will be developed that exploit the recent discovery of silver-promoted coupling reactions of thioamides. A novel late-stage, chemo-selective assembly of N-glycosylated asparagine residues in peptides and proteins will also be developed. The outcomes of this research will lead to breakthroughs in synthetic methodologies for the assembly and functionalisation of peptides and proteins, thereby enabling access to a range of homogeneous, post translationally modified proteins though total chemical synthesis. These research outcomes will expand Australia's research capability and global competitiveness in the field of biotechnology, delivering significant benefits to the third largest manufacturing sector in Australia.Read moreRead less
Interfacial and Structural Changes During Digestion of Milk-like Systems. This project aims to enhance the understanding of the behaviour of milk and milk-like systems during digestion. Utilising new Australian research infrastructure the project aims to unlock the complex behaviour across different types of milk (including human breast milk) and infant formulae, linking how enzymes behave towards fat droplets and the consequences for lipid structuring and nutrient transport.

This project aims to enhance the understanding of the behaviour of milk and milk-like systems during digestion. Utilising new Australian research infrastructure the project aims to unlock the complex behaviour across different types of milk (including human breast milk) and infant formulae, linking how enzymes behave towards fat droplets and the consequences for lipid structuring and nutrient transport. The rational design of systems that function much more closely to human milk will enable the development of new products with flow on benefits in human nutrition and increased utilisation of products from our dairy industry.Read moreRead less

This project aims to determine how nanoscale objects which mimic the surface of cells behave in biologically relevant environments. This project expects to generate new knowledge in physical chemistry by complementing innovative surface chemistry design and characterisation with data science approaches. The expected outcome of this project is identification of the mode of interaction of these biomimetic objects with cells, which may then reveal a new pathway for the delivery of pharmaceuticals. This could provide significant future benefits in the treatment of neurological diseases and bacterial infections, by overcoming the barrier that the cell surface presents to the uptake of many medicinal drugs.Read moreRead less
Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities.

Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will apply novel hydrogeophysical and hydrochemical methods, and computer modelling, to investigate the source aquifer of, and fate of discharge from the Doongmabulla Springs Complex (DSC), located in an area of future development. Project results will inform spring vulnerability to development pressures and climate effects.Read moreRead less
